Abstract

La présente invention concerne un ventilateur axial comprenant un moyeu conçu pour être mis en rotation autour d'un axe central, ainsi qu'une pluralité de pales s'étendant radialement vers l'extérieur à partir du moyeu et disposées autour de l'axe central. Chacune des pales comprend une emplanture, une extrémité, un bord d'attaque entre l'emplanture et l'extrémité et un bord de fuite entre l'emplanture et l'extrémité. Chacune des pales définit un rayon maximal entre les extrémités de pales et l'axe central. Chacune des pales définit un angle oblique décroissant dans les 20% extérieurs du rayon maximal. Le rapport entre le pas de pale et le pas de pale moyen augmente d'une valeur minimale à une valeur maximale dans les 20% extérieurs du rayon maximal. La valeur maximale est supérieure à la valeur minimale de 30 à 75% approximativement.
